RAIN-WATER CUT-OFF.

SPECIFICATION forming part of Letters Patent No. 395,998, dated January 8, 1889.

Application filed October 23, 1888. Serial No. 288,928. (No model.)

To all whom it may concern? Be it known that I, DANIEL W. ROLAND, of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in RainJVater Cut-Offs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in rain-water cut-oit's; and it consists in a box provided with a lid, to which the inlet-pipe is attached, and having a waste-pipe and an outlet-pipe extending from its bottom, a rocking lever pivoted in the box, valves connected to the opposite end of the lever to alternately close the waste and outlet pipes, a weight connected to the underside of the valve which closes the waste-pipe, and a bucket provided with an automatically-operating valve connected to the under side of the valve which closes the outlet-pipe, all of which will be more fully described hereinafter.

The object of my invention is to provide a cut-off which can be made to pass off all of the water through the waste-pipe or through the outlet-pipe into the cistern, and in which waste-pipe a bucket with an automaticallyacting valve is placed for the purpose of automatically changing the flow from the waste to the outlet pipe.

Figure 1 represents a plan view of a box and its attachment, with the lid removed. Fig. 2 is a vertical section taken through the center of the box. Fig. I is a plan view of the cover of the box alone.

A represents the box or body of the cutofl', which is provided with a tightly-fitting lid or cover, B, to which the inlet-pipe (1, provided with a removable strainer, is secured. Any number of waste-pipes may discharge into the inlet-pipe, and from this inlet-pipe C the water passes directly into the box A. From the bottom of the box A extends the outlet-pipe D and the waste-pipe E. Through the bottom of the box A is made the opening F, through which the water passes to the waste pipe, and the edge of this opening is flush with the bottom. The opening G through the bottom of the box A, and through which the water passes to the outlet-pipe D, has a raised edge or flange around it, so that the valve which controls the flow of water through this outlet-pipe I) will lit snugly therein and prevent any possible leakage.

Pivotcd inside of the box A is a journal or bearing, ll, to which the lever I and the deflector .l' are secured. The deflector consists of a flat plate of any suitable width, which is turned toward either end of the box, according as to whether it is desired to deflect the water passing through the pipe 0 toward the waste or outlet pipe. This deflector being rigidly secured to the pivoted support or bearing ll, it is only moved when the deflector is turned so as to close one of the openings and open the other. In order to hold this deflector in the position into which it has been adjusted, there is secured to the inner side of the box a spring, L, which is preferably shaped as shown, and which bears against the end of the deflector for the purpose of preventing it from being too readily moved. \Vhen the valve of the outlet-pipe is closed, the end of the deflector catches behind the shoulder on the spring; but when the valve which closes the waste-pipe is closed the spring merely exerts a frictional contact against the end of the deflector.

To each end of the rocking lever l are secured a suitable number of links, and to the lower end of the links are secured the valves N O, which are prefm'ably made conical and of any suitable material that may be preferred. These valves are made conical, so that they will not be so liable to stick or to freeze during cold weather. The valve N' is made slightly smalh'sr than the opening through which it is to pass, so that the water can leak past it; but the valve 0 closes theopening G tightly so that there can be no possible leakage. To the under side of the valve 0 is loosely secured a weight, Q, so as to draw the valve down upon its seat with sufficient force to stop any leakage. To the under side of valve N is loosely secured a can or bucket, R,

provided with a cover, and a lip or flange, S,

whieh projeets toward the inner side of the pipe E. The opening into the can or bucketis just sut'tieient to allow a small i uantity oit' water to run into it, and thus till the can or hueket slowly, so that the tirst of the rainwater will have a ehanee to pass olti through the waste-pure, and thus ('arrv away the dirt that had aeeulnulated upon the roof and in the waste-pipes. This (an or hueket when tilled with water is sut'tieient to overcome the weight Q, secured to the valve 0, and thus eause the valve 0 to open and the one N to elose. This tan or bueketli is seeured to the under side ot' the valve N by means of a spring, i so that the weight of the liiueket will eause it to drop downward in the wastepipe lartht'rr than it otherwise would do, and thus allow the bent wire t to drop below the notch Y in the grooved extension \V, whieh pro j et-ts down from the lower end of the waste:- pipe upon one side.

llhrtiiugh the inner side ot' the bucket at its bottom is made a small leak-hole, o, for the eseape of the water in the bucket or can, and seeured to the bent wire i is a small valve, X, for the purpose ot' (dosing this opening when thehuek etorean is raised upward in the pipe E by tilting of the lever I. The wire 't' is shaped as shown, so that when the bueket or ean H is raised into the pipe the shoulder Y upon the wire will be toreed inwz'irdtv toward the but'ket by the side of; the waste-pipe or extension \V, and thus tort-e the valve X against the leak-hole, so as to stop all turther leakage of the water. .Vhen the bueket R is de-.

pressed in the pipe E, the shoulder Y upon the wire I' sinks below the noteh Y in the extension W, and then the valve X springs outward with the wire from against the side of the bucket. While in this depressed position the leak-hole is open, and the water which has run or is running into the hueket ean leak out. As the valve N does not close the open ing to the waste-pipe tightly, sut'tieien t water can always leak around past the valve so as to keep the bueket l1 full. The weightot' the water in the bueket serves to eounterbalanee the valve 0 and the weight Q, seeured to it, and thus the opening to the wasttspipe will be praetieallv elosed, while the opening (5t to the mitlet-pipe I') will be opened.

When it is desired that all of the water [towing into the box A shall, pass ottf thrtnigh the elosed pipe,the end of the lever Lhaving the valve seeured to it, is depressed by the rod Z, whieh extendsup through a slot in the (-over and is provided with a bend or erook, in which a rod or wire, A, is made to eateh tor the purpose of looking the lever l in position,

and thus prevent the weight of the water in the bueket R. from opening the valve The extension \V is made U-shaped, so that the wire U' will catch therein, and thus prevent the bueket or can from turning around.

The spring it may he made to hear against an upwardly-exte1uling lug seeured to the rt'ieking hearing,instead of against the deileet'or itself, for hi'ilding the valves in proper position by frictional etnit'aot. The sides of the grooved extension W extend slightly helow the lower end of the groove, as shown, to .i tlllll a guide for the wire I", so as to always guide the wire into the groove.
